linux:vdr_konflikt_mail

Send Mail when VDR timer-conflict occurs script-based

  • Send Mail when VDR timer-conflict occurs.

Context

Problems:

  • I'm using my vdr without a client and without OSD.
  • I doesn't find a pleasant possibility to send a mail when a conflict occurs.
  • By using epgsearch, a conflict could arise without noticing.
  • A existing Perl script wasn't possible to use for me because I have installed postfix and mailx not sendmail.

Prerequisite

  • All logs produced by vdr are collected by syslog-ng into a single file so that can be analysed.

Syslog-ng.conf (part of it):

filter f_vdr {
  program(".*vdr.*");
  };
destination d_vdr {
  file("/data/syslog/vdr/$YEAR-$MONTH/vdr.log.$DAY"
  owner(root) group(root) perm(0644) dir_perm(0755) create_dirs(yes));
  };
destination d_vdr02 {
  file("/data/syslog/vdr/$YEAR-$MONTH/$FACILITY/vdr.log.$DAY"
  owner(root) group(root) perm(0644) dir_perm(0755) create_dirs(yes));
  };
log {
  source(s_all);
  filter(f_vdr);
  destination(d_vdr);
  destination(d_vdr02);
  };

Monitoring the log

  • Every 30min, or something like that, vdr checks for timer-conflicts (It's a German System)
Apr  2 17:20:00 vdr: [6734] EPGSearch: timer conflict check started
Apr  2 17:20:00 vdr: [6718] info: 1 Timer-Konflikt(e)! Erster am 02.04 20:38. Anzeigen?
Apr  2 17:20:08 vdr: [6734] EPGSearch: timer conflict check finished

Analysing the log isn't complicated:

  • mailx only works without additional options when postfix is configured properly
